Title
(EN) FUEL SUPPLY APPARATUS FOR VEHICLE
(FR) APPAREIL D’ALIMENTATION EN CARBURANT POUR VEHICULE
Abstract
(EN)
Fuel pipes (190 and 192) guide fuel from a fuel tank (165) provided in a rear area (600R) of the vehicle to a low-pressure fuel supply system (11) and a high-pressure fuel supply system (12), respectively, for injecting the fuel to an engine (10) provided in a front area (600F) of the vehicle. A branch point (Na) between the fuel pipes (190 and 192) is arranged in the vicinity of the fuel tank (165) to secure a long pipe length between the low-pressure fuel supply system (11) and the high-pressure fuel supply system (12). This can suppress variation in fuel pressure at the low-pressure fuel supply system (11) attributable to the fuel that is discharged from the high-pressure fuel pump (200) within the high-pressure fuel supply system (12) back to the fuel pipe (192).
(FR)
La présente invention concerne des tuyaux d’alimentation en carburant (190 et 192) qui guident le carburant à partir d’un réservoir à essence (165) prévu dans une zone arrière (600R) du véhicule jusqu'à un système d’alimentation en carburant basse pression (11) et un système d’alimentation en carburant haute pression (12), respectivement, pour injecter le carburant vers un moteur (10) prévu dans une zone avant (600F) du véhicule. Un point de branchement (Na) entre les tuyaux d’alimentation en carburant (190 et 192) est agencé dans le voisinage du réservoir à essence (165) pour fixer une longueur de tuyau importante entre le système d’alimentation en carburant basse pression (11) et le système d’alimentation en carburant haute pression (12). Ceci peut supprimer la variation de pression de carburant au niveau du système d’alimentation en carburant basse pression (11) attribuable au carburant refoulé à partir de la pompe à carburant haute pression (200) à l’intérieur du système d’alimentation en carburant haute pression (12) vers le tuyau d’alimentation en carburant (192).
